Specification of Letters Patent.

Patented July 13, 191 5.

Application filed February 17, 1914. Serial No. 819,144.

In the manufacture of collapsible boxes it is one of the primary conslderat1ons,as1de from the features of collapsibility 'of the box, to provide cheapness of construction and strength. In my prior Patent, Number 1,063,845, I have described and claimed a collapsible box of fibrous material in which a reinforcing fold is formed out of the material of the box at the junction of the flaps and sides to strengthen the walls of the box and space them from the supporting surface, so that the impact is received by the layers of the foldsinstead of being received directly by the walls or sides proper. In the present invention, aconstruction is provided whereby the folds are made to.

encircle the corners of the box, and thus further strengthen the same without the aid of auxiliary corner pieces such as described in my patent above mentioned.

In carrying out the invention, I make a doublescore at the junction of the sides of the box to form projecting ridges at the junction of the sides. These ridges not only serve to form strengthening means for the box at its longitudinal edges, but also permit the folds to easily bend around the corners without disturbing the material to any considerable extent.

- In the drawings illustrating this invention, Figure 1 is a perspective view of the blank with the scoring and folding completed, previous to the joining of the free edges of the sides. Fig. 2 is a perspective view illustrating the box as set up. Fig. 3 is a fragmental section taken along line 3-3 of Fig. 4. Fig. 4 is a fragmental section taken along line 414 of Fig. 2.

My improved collapsible box may be made of corrugated board, fiber board-or anyother board of fibrous material.

flaps 11 which close the ends of the box' afterthe same is set up. At the junction of each pair of the sides are formed two longitudinal scores 12 and 13 between which is formed a projecting ridge 1-1 substantially U shape in section, the outer surface of which extends at an angle to the joiningsides. This projecting ridge serves to take up the shock and impact from the sides and forms a sort of cushion therefor. Between the sides and flaps is formed at each end of the box, a continuous fold 15 which rein; forces the ends of the box and also spans the corners and reinforces the same.

As will be noted, the ridges ll relieve the sharpness of the corners of the box and permit the fold 15 to round the corners in a gradual curve 15 thus relieving the material of the fold from the strain which would otherwise develop in bending around a sharper corner. The folds are preferably secured to the sides by suitable fasteners such as staples 16. However, it will be understood that these fastening means may be dispensed with, as, when the free edges of the sides are fastened together, thefold will be held in place by the disposition of the material itself. v 7

'It will thus be seen that I have provided a collapsible box of fibrous material which is well reinforced and cushioned from impact and is withal cheaply manufactured and is practical in use. The entlre box may be formed of one integral piece of material,

portions of which accomplish all the required strengthening and cushioning functions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A collapsible box of fibrous material having sides and end flaps, a fold formed of the material of the box at the junction of the sides and flaps to reinforce the ends and corners of the box, and a rigid longitudinal fold formed of the material of the box for reinforcing the longitudinal edges of the sides.

2. A collapsible box of fibrous material having sides and end 'flaps, a continuous reinforcing fold at the junction of the sides and flaps, angular sections formed by parallel crimps between the adjacent sides at the corners, said folds spanningsaid angular sections.

I 3. A collapsible box of fibrous material having sides and end flaps, a continuous reinforcing fold at the junction of the sides and flaps, U shaped angular sections formed by parallel crimps between the adjacent tion of the sides and flaps, said folds spanning the projecting ridges to form a gradual bend between the sides.

5. A collapsible box having sides and end flaps, U shaped rigid projecting ridges formed out of the material of the box at the junction of the sides, and continuous folds formed out of the material of the box'at the junction of the sides and flaps, said folds spanning the U shaped projecting ridgesto form a gradual bend between the sides.

6. A collapsible box formed of an inte'- gral sheet of fibrous material comprising side and end flaps, substantially U shaped pro ecting ridges connecting the sides and separated therefrom by crimps, and continuous'folds at the junction of the sides and flaps, said folds spanning the projecting ridges and bending gradually from one of the adjoining sides to reinforce and protect the corners of the box.

7. A collapsible box formed of an integral sheet of fibrous material comprising side and end flaps, substantially U shaped rigid projecting ridges connecting the sides and separated therefrom by crimps, and 8 shaped continuous folds at the junction of the sides and flaps, said folds spanning the projecting ridges and bending gradually from one to the other of the adjoining sides to reinforce and protect the corners of the bOX.
